No opinion on the Kitchen, although I suspect you could make a small kitchen for nearly 5K if you did all the work yourself and got used appliances off of craigslist
Regarding your expenses, they seem somewhat high to be me as listed.
300 for cell phone + insurance = 100 for cell phone, 200 for car ??? That seems high for both the phone, and the insurance. I pay ~100 per month for 2 cars.
240 / month for gas = $ 60 / week = more than 1 tank of gas per week. Presumably a lot of this is commuting to work. I recommend looking at buses, van pools, or carpooling to get to work. Boeing will subsidize $60 / month for a bus pass or van pool, and you can put more money in pre-tax, so that might save some commuting costs
$500 / month on entertainment = 125 / week = 3 bar or restaurant outings at $40 / time each week ? I suspect that there is opportunity to economize here
living with the parents is a great way to save money. You're probably saving $500-$800/month doing that, so good job!
